Abstract

Inroduction & Objective: Sardines and other MICROFILIDAE have very important ecological role inmarine ecosystems because they are first consumers in marine food chain Therefore there is a disturbancein the food chain in the marine environment and possibly a decrease in the population of fishes such as tuna. There are 10 species of CLUPEIDAE in the Gulf and the Sea of Oman, among which genus Sardinella isdominant. Considering the significant climatic differences between the PERSIAN GULF and the OMAN SEA, thepresent study was conducted to investigate the possible MORPHOLOGICAL VARIATION and to create subpopulationsin the distribution area of rainbow sardine species. . Material and Method: During winter 90 and spring 91, 64 rainbow sardines were collected from Jask(Oman Sea) and Lengh (Persian Gulf) ports. Morphological traits were measured and recorded with 0. 01mm precision and digital scale with accuracy of 0. 001 g. Data were analyzed by multivariate analysis ofMANOVA, PCA main variables test and standard separation test using SPSS software. Results: Morphological analysis and variance analysis showed a significant cline at the level of P <0. 05 inall traits between the two regions. Based on the post hoc test and the main components all traits variation issignificant. On the other hand, Claster analysis and a standard trick test based on morphological traitsseparate two regions from each other. Conclussion: The observed diversity in morphological traits of this species can be due from salinity andheat stress in the PERSIAN GULF and the higher availability of nutrients and moderate temperature of thewater as a result of the upwelling of the summer Monson in the sea Oman affects. This conclusion isconsistent with other studies on other large fish in the PERSIAN GULF and the OMAN SEA. Also, the ability ofthis species to live in coastal areas and estuaries can reduce the possibility of mixing different populations ofthis species. The results can be illustrated by the fact that this species has sub-populations in its widespreaddistribution that can form sub-species in the distribution area of this species.
